WINDMHIL.

Application filed December 29, 1922. Serial No. 609,554.

This invention relates to features of wind mill construction.

This invention has utility when incorporated in back geared mills of the self contained or housed type.

Referring to the drawings:

Fig. 1 is a fragmentary view of an embodiment of the invention in a wind mill;

Fig. 2 is a section on the line II-II,

Fig. 1;

Fig. 3 is a view on the line III-III, Fig. 2; I

Fig. 4 is a section on the line IV-IV,

Fig. 5 is a section on the line V-V, Fig. 2; and f Fig. 6 is a section on the line VT-rVI, Fig. 2.]

A wind mill tower 1 is provided having a i cap 2. This cap 2 has a pivot bearing 3 and thereabove and concentric therewith, 2. lateral bearing 4 with which tubular stem 5,

coacts as a support for main or lower housing 6 of the wind mill structure proper. 2 The upper portion of this housing 6 has a peripheral flange 7 which has bosses 8 in ali nment for carrying stub shaft 9. Gentra ly of this housing 6 there rises a portion 10 having a top opening 11 therein in alignment with tubular portion 12 of the stem 5. This hollow central portion 10 extends over to a wall of the housing 6 away from the stub shafts a c 'lindrical seat portion 13 in alignment 5 wit a second cylindrical seat portion 14 in an extension 15 of the housing 6, and the opening 11.

. Wind wheel 16 is shown as having overhanging hub 17 provided with boss 18 fixed 40 with main wind wheel shaft 19. This shaft 19 is mounted in a pair of cylindrical roller bearings20. This pair of roller bearings 20 is mounted in sleeves 21 in respective aligned seats 13, 14. of the housing portion with the main housing 6. The outer sleeve 21 has about the shaft 19, a groove 22, tonreceiving packing 23 there.-

sembled with crosshead 9 and said portion has by serving to prevent lubricant from the housing 6 escaping or working out upon the wind wheel 16. This outer cylindrical sleeve 21 is fixed in position with the extens1on 15 from the housing 6 by a set screw 24.

Keyed to the drive shaft 19, and on each side. of the inner-bearing 20, is a pinion 25. Each of these pinions 25 is in mesh with a gear wheel 26. Each gear wheel 26 is mounted upon a cylindrical roller bearing 27 carried by the aligned stub shafts 9 in the housin 6. Each of these gear wheels 26 is held In position on its stub shaft 9 by washer 28. Extendin to engage the antifriction bearing 27. hese washers 28 are held by upset end portions 29 of the connecting rod 33 upwardly extending to,

engage a pin 34 with which it is held assembled by Washer 35 and a key 36, outward therefrom. The pitmans 33 are thus as- 37 This crosshead 37, as operated by the pair of pitmans 33, slides upward and downward upon guide rods 38, 39. The guide rod 38 is anchored in a boss 40 on top of the central portion 10 of the housing 6 while on the opposite side of the opening ll from this opening 40 is boss 41 for mounting the guide rod 39."

Fast to this crosshead 37 and downwardly therefrom through the opening 11 and tubular stem 5, is angle reciprocable rod 42 extending below the cap 2 to a swivel bearing 43 thereby connected to pump rod 44. Through the tubular swivel bearing 42 is chain or flexible pull-out line 45 extending upward between t e flanges of the angle rod and through the tubular portion 12 of the stem 5 to pass out between the depending cheeks or flanges 46 from the housing 6; thence over guide roller 47 and about guide roller 48 to rudder 49 mounted to swing upon trunnions 50, 51, integral with the main housing 6. Pulling of the chain 45 swings the rudder 49 toward the wind whee] l6'to throw the wind wheel to out of gear.

The cross head 37 has a horizontal extension 52. Nuts 53, 54:, serve to anchor tubuplunger or piston rod 55 to the cross head extension 52. This piston rod 55 extends downwardly into barrel havin threaded engagement with extensioa 57 of well por-;

lubricant as forced upward in and ough this tubular piston rod hoods Lite ways 5 lin the cross head 52 over to luate the two guide rods 80,

way from this War 64:, cant further to slop over, only to luericate the pitman 33 and the pin but to spatter out upon. the gears 26, and by them be taken over to the pinions 25 and thus selectively lubricate the entire transmission of thi wind mill.

lailounted on this main one piece housing cap or extension section 66, completing ne enclosing of the transmission mechanism having outward flange 6' and inner nge 68 for engagement with this lower section 8 by snugly fitting thereover,

The throwing-in of the rudder i9 is limited by rod 69, coacting with the stem l0 fast with the housing 6.

The painol parallel guide rods 38, 39, have their upper portions spaced and still"- ened. by cross bar 71.

Upset end l2 or" the main wind shaft 19 takes the thrust of the shaft against the housing 6 as well as retains the inner terminal pinion 25 in position against slipping 06 said shaft.

A in;

In the wind motor structure as herein dis-- closed there is shown a main frame 6 which permits simplified construction for mounting positively the parallel shafts of the transmission mechanism. This structure is economically produced by machine work for the seats of the shalt and stub shafts may be dressed and simultaneously aligned in a single jig operation. When the entire trans mission mechanism is housed, the closure cap efi'ectively shields the mechanisms from the weather. 'lhe mill is self lubricating. It may have long periods of opration without any attention whatsoever, As protected from the weather it is of long life, economical for upkeep and of operation.

W hat is claimed and it is desired to secure by Letters Patent is:

1. A wind motor open top main housing section unit, a closure cap for the unit, trans 1lSSl0I1 mechanism mountedin the unit including a crcsshead movable in the cap, and having bearings, a-lubricant way above said bearings, and from the way to said hearings, and crosshead actuated pump means for supplying lubricant to the crosshead lubricant way.

2. A wind motor embodying a housing having a chamber, a crosshead, a tubular rod rigidly connected to the crosshead, and a guide in the chamber into which the rod extends i 3. A wind motor embodying a housing having a chamber, a crosshead, a tubular rod rigidly connected to the crosshead, and a guide in the chamber into which the rod ext-ends, said crosshead being provided with ways in communication with said rod,

at. A wind motor embodying a housing providing a chamber as a lubricant reservoir, said housing integrally therewith a downwardly externally tapered to for extending tubular stem provide a seat, gearing e motor in said housing, shafts for the 1g hearings in said housing, and iovidiug a socket the i embodving a housing pro .iher as lubricant reserhaving integral therewith wr, said housin a downwardly extending tubular stem, support for the stem, said housing having exterior of the chamber a laterally extending opening to said stem, and pull-out means extending through said opening into said stem and thence through said support.
